Provided are a reductive amination catalyst for preparation of polyether amine and its preparation method. According to the reductive amination catalyst, a reductive amination reaction includes: enabling polyether polyols to undergo a hydroamination reaction in presence of the reductive amination catalyst to prepare polyether amine. The reductive amination catalyst includes an MgAl.sub.2O.sub.4 carrier, Ni, Pd and Cu active components loaded thereon. -Al.sub.2O.sub.3 modified by MgO is used as the carrier for the amination catalyst, and the modified MgAl.sub.2O.sub.4 carrier has characteristics of high temperature resistance, high mechanical strength and low surface acidity, which can better adapt to the high temperature and high pressure reaction conditions required for low-carbon alkane dehydrogenation. In presence of the catalyst, the temperature of a reaction system is low, and the activity or selectivity of the catalyst is suitable for oligomeric oxypropylene ether. The Raw materials and catalyst facilitate the preparation of low-color-value polyether amine.
